INIR7 Refrigeration Leakage Detection Sensors

Amphenol SGX Sensortech INIR7 Refrigeration Leakage Detection Sensors are user-friendly digital gas sensors based on the Non-Dispersive Infra-Red (NDIR) technology. These sensors feature a 4.5VDC to 30VDC supply voltage range, up to 50ppm high resolution, 200ppm detectivity level, and 120kPa maximum operating pressure. The INIR7 sensors feature R290 or CO2 detection, CAN or Modbus communication, temperature compensation, high accuracy, and simple integration into the end-user system. Typical applications include residential gas monitoring, heat pumps, refrigeration, chill cabinets, vending machines, cold storage systems, air conditioning, automotive, and R290 or CO2 leakage detection.
